Rear Wiper Intermittent Delay Timer Mod

[toy_toronto]

I am no expert in electronics whatsoever but the rear wiper delay is quite simple to achieve actually once you find the right module/kit.

Right now, if you turn the rear wiper switch ON and shut it OFF while the wiper blade is in the middle of the cycle, the motor still completes the cycle and returns the blade arm to "home" position. Wouldn't it be nice if there was a basic circuit that automatically turns the rear switch ON/OFF for you at specific interval?

Well I'm currently bench-testing a control module that does exactly that. It sends approximately half a second pulse or "momentary short" to the rear wiper switch connectors that activates the motor. The delay interval can be adjusted from 3 to 30 seconds for intermittent function via potentiometer which also happens to have it's own dedicated ON/OFF switch built-in. You still have the option to use the factory rear wiper switch as you would normally, but now you get a 2nd option where you use the module's potentiometer ON/OFF switch instead and set the wiper delay interval.


I'll post more details when I get everything installed and finalized this weekend -- but so far everything seems to be working perfectly without any issues.

P.S. picture below shows where the "short" happens when the rear wiper switch is turned ON:
